Character:

Sima Yi makes his debut appearance in the second installment of the game. He is portrayed as a cunning, ruthless and extremely arrogant strategist who boasts endlessly about victory and insults his enemies with derogatory words. He is also unable to accept defeat and he likes to dismiss the failure of his plans with the excuse that it is merely another cog in the gears of an upcoming grand tactic that he has devised.
